Relentlessly they jammed old washers and beer checks into the slots. In its4irst year in business, theAutomatic Canteen Corporation of America took in more than $30,000 in worthless slugs. Nathaniel Leverone, chairman of the board,x groaned, "Whenever a budding inventive. . genius goes wrong, he wants to beat a vending machine!" By then, machines were dispensing candy bars, peanuts, chewing gum, and even cigarettes. Engineers set out to teach thesejme. chanical salesmen not to take wooden nick-e- ls machine vending The battle on. In machine shops where brass, bronze, and copper were available, workers-puncheout disks. Vending machines gob- bled these up and handed over, everything they had. Engineers countered by setting up a magnetic field around the inserted coin. Only silver and nickel could get through. But workers In a Connecticut factory resorted to slugs of precisely those metals! Their company made coins for a number-o- f South American countries. The machines retreated from the plant, never to return. Elsewhere, it seemed machines were winning the battle against slugs.

They installed a contrivance with three fingers, which felt both sides of every object inserted, and rejected many phonies. But "Three-fing- er Jack" did not keep a man from slipping in a smooth slug the dimension of a nickel. Engineers insetted a magnet which seized all iron slugs and tossed them out the coin return. Some customers thrust lead, aluminum, and alloy slugs into the slots. The machines defended themselves.

In just about any rail or air terminal a machine will issue an insurance policy. And for lunch, a worker.can buy sandwiches, hot beef stew, pie, and a steaming cup of coffee. Some housewives need not go into the crowded supermarkets. Out in. front of the neighborhood store are machines that sell milk, bread, canned goods, and frozen foods. All they have to do is put in the right coins. In Chicago, a woman stepped up to such a machine and selected a canned ham priced at $1.05.
